1. Does the body feel anything during radiotherapy?
Radiotherapy is the use of linear accelerator to emit X/ γ Radiation, through the "invisible knife" of radiation, can "cut" the tumor in a small range with a high dose of radiation. The patient has no wound and does not need anesthesia. Because of its "invisible and intangible" characteristics, it is known as the "invisible scalpel". Therefore, the patient does not feel during radiotherapy.
2、 Is radiotherapy effective?
Radiotherapy not only has a wide range of treatment, but also has an obvious effect. Its contribution to the cure of tumors is second only to surgery. According to the statistics of WHO, 45% of patients with malignant tumors can be cured, of which 22% are cured by surgery, 18% by radiotherapy, and 5% by chemotherapy. Whether it is suitable for radiotherapy depends on the type and stage of the tumor and the patient's physical condition.
3、 Does radiotherapy kill 1000 enemies and lose 800?
For the criticism of radiotherapy, people say most that radiotherapy will kill a lot of normal cells as well as cancer cells, so the treatment effect is often not worth the loss. This is probably one of the root causes of people's prejudice against radiotherapy. With the rapid development of radiotherapy technology, the problem of "injuring" normal cells by mistake has been well solved in the era of precise radiotherapy.
4、 How many times does radiotherapy need to be done?
The number of times of radiotherapy is determined according to the type and stage of the patient's tumor and the patient's own conditions. Generally, the patient will receive 20 to 30 times of radiotherapy. If it is suitable for SBRT or SRS, it only needs to be done within 10 times.
5、 Is the side effect of radiotherapy equivalent to that of chemotherapy?
We often see on TV that cancer patients will have severe side effects such as hair loss, nausea and vomiting after chemotherapy, while radiotherapy and chemotherapy are often compared because there is only one word difference. Many people believe that radiotherapy will also have severe side effects. Although radiotherapy patients may also have some side effects, they are mainly local reactions. The side effects of radiotherapy are often related to the irradiation site, irradiation time and dose. As long as the symptomatic treatment is timely, there will be no sequelae.
6、 Is there any radiation in the radiotherapy department?
The key weapon for the radiotherapy department is the linear accelerator, which generates high-energy electrons to bombard tungsten targets through high voltage, thus generating high-energy X-ray and electron lines. X-ray and electronic wires will only be generated when power is on, and will disappear after power is off. Moreover, the radiotherapy room is safe and effective, and there is no radiation outside the room.
7、 Does the radiotherapy patient have radiation?
Some patients do not dare to hold their children when they come home after radiotherapy. They feel that their own radiation will affect their children, and they also dare not contact others. There is no radioactive source, no ray, no radiation, no residue in the body and no secondary radiation on the patient's X ray or electron line generated by the linear accelerator.
8、 What is the difference between radiology and radiotherapy?
The difference between radiology department and radiotherapy department is one word. Radiology is a medical technology department used for disease diagnosis, such as CT, X-ray and other examinations. Radiotherapy department is a clinical department that uses radiation to treat tumors. Patients should choose the tumor radiotherapy clinic when registering.
9、 Can I stop during radiotherapy?
Generally, you can't stop. The treatment mode of radiotherapy is formulated repeatedly and accurately. If the patient stops radiotherapy for several days, the treatment effect will be affected. If the patient has obvious radiotherapy reaction or other complications, the treatment must be stopped for no more than a week.
10、 Does radiotherapy need to be taboo?
Radiotherapy patients should choose a light, digestible and nutritious diet to ensure various nutritional needs during treatment. However, special attention should be paid to some tumors, such as gastrointestinal tumors or tumors that may damage the digestive tract during treatment. Attention should be paid to reducing the burden on the digestive tract and avoiding the damage of dry and hard food.
